Abstract
The utility model discloses a hand-held rectal speculum for a rat, which comprises a speculum body and a handle, wherein the speculum body takes the shape of a cylinder; a connecting cap is arranged at the tail end of the speculum body; the bottom thereof is hinged with the handle; an opening is arranged on the side wall of the speculum body; the handle takes the shape of a frame; one end of the handle is hinged at the bottom of the speculum body; the other end of the handle takes a shape matched with the connecting cap; and the handle is buckled on the connecting cap of the speculum body. Compared with the prior art, the utility model has the characteristics of simple structure, convenient observation and medicine taking, safety and reliability.
Description
One, technical field
This utility model relates to a kind ofly can fully expose the inner visual field of rat rectum, is suitable for observing the rectum internal structure, internal rectum is drawn materials and administration, can effectively prevent the hand-held rectal speculum of rat that rectal speculum is deviate from again.
Two, background technology
In medical experiment research, the inner visual field of rat rectum difficult exposure, but the research of duplicating with pathogenesis such as rectal lesion such as tumor, inflammation and treatment of rectum internal organs pain model all needs fully to expose the inner visual field of rectum.In the research of rectum internal organs pain model, need under rectal mucosa under the visual condition, duplicate Encelialgia by drug administration by injection, and get the corresponding site rectal mucosa and carry out Related Experimental Study, research Encelialgia pathogenesis and treatment are had important function; In pathological changes such as rectal neoplasm, inflammation pathogenesis and the treatment research, need fully expose under the situation of the inner visual field of rectum, carry out that diseased regions such as rectal neoplasm, inflammation are observed, drawn materials, administration research, and can be at body, continuous observational study, avoid putting to death the generation of animal, guarantee experiment effect because of exposing the inner visual field of rectum.But the specula that still lacks the effective exposure rectum visual field at present, the inner visual field of rectum exposes bad, influences the experimentation quality to a certain extent.
Three, utility model content
This utility model provides a kind of modern design, and is simple in structure, easy to operate, safe and reliable, and practical rat is handed rectal speculum.
Technical solution adopted in the utility model is in order to achieve the above object:
A kind of rat is handed rectal speculum, comprises specula body and handle, and the specula body is a cylindrical tube shape, and it is hinged that the specula end of body is provided with attachment cap, bottom and handle, and the specula body sidewall is provided with opening; Handle is the frame type, and an end is hinged on the specula body bottom, the shape of the other end for matching with attachment cap, and handle is buckled on the attachment cap of specula body.
Handle and specula body are hinged, can adjust angle between the two, one hand-held handle, a hand-held specula body during use, the specula body of firmly can realizing by handle is that rotating shaft rotates at internal rectum with its axis, can carry out in all directions observation to the rectum periphery, hand-held simultaneously handle has prevented that also rectal speculum from detaching rectum.
Specula body and attachment cap be for being threaded, and make for transparent material; Specula body sidewall opening is circular or oval.
Specula body attachment cap is detachable connection, can select to have or not the attachment cap dual mode to insert specula, the opening that transparent material is made and is provided be convenient to diseased regions such as intestinal neoplasms, inflammation observation, draw materials, administration.
Attachment cap and handle top are arc-shaped structure.
Arc-shaped structure helps this rectal speculum and enters rectum by anus, and the organ to rat does not damage.
The attachment cap top is provided with a groove, and the top card of handle is buckled in the groove.
This specula body can rotate to frame type handle the top of specula body when not using, make in its groove that is buckled in attachment cap, is difficult for deviating from.
Four, description of drawings
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is an elevational schematic view of the present utility model;
Fig. 3 is a schematic top plan view of the present utility model.
Five, the specific embodiment
As shown in the figure: a kind of rat is handed rectal speculum, comprises specula body 1 and handle 2, and specula body 1 is a cylindrical tube shape, it is hinged that specula body 1 end is provided with circular-arc attachment cap 3, bottom and handle 2, specula body 1 is provided with female thread, and attachment cap 3 is provided with external screw thread, and both are threaded; Specula body 1 sidewall is provided with circular or oval-shaped opening, helps intrarectal observation, administration and draws materials; Handle 2 is the frame type, and an end is hinged on specula body 1 bottom, and the other end is the circular shape that matches with attachment cap 3, and attachment cap 3 tops are provided with a groove, and handle 2 can and be buckled in the groove of attachment cap 3 of specula body 1 around the rotation of specula body 1 bottom.
Unobstructed when making specula enter the rat rectum, along sliding, alleviate the damage of specula to rectum, the bottom margin of attachment cap 3, specula body 1 end face and specula body 1 sidewall opening are provided with slick and sly excessive circular arc.
This utility model can adopt the light-duty hard material of stainless steel material or transparent material or other to support, and can carry out high temperature, high pressure, medicine sterilization.
During use, open the handle 2 that is buckled in specula body 1 end attachment cap 3 grooves, on the other hand hand-held then specula handle 2, coating lubricating oil on specula body 1 end and the attachment cap 3, rotation also uses suitable dynamics that this specula is slowly inserted the rat rectum through the rat anus, under the irradiation of light source, hand-held handle 2 rotates specula body 1 gently, by the opening of specula body 1 can observe clearly rectum inside various piece, orientation, administration, operation such as draw materials.
Observe as needs that the specula body is darker to go out the rectum inner case, the removable attachment cap 3 of laying down specula body 1 inserts rectum and observes and get final product.
